VS 2010 Why Does WebClient.DownloadString Remove Part Of HTML's Source

Nov 13, 2011

When I go to webcrawler.com and search for something, then look at the source code, a chunk of HTML similar to this displays the search results:

<div id="webResults">
<div class="searchResult webResult">
<a class="resultTitle" data-icl-coi="540" data-icl-cop="results-main" href=[website] target="_blank">[title]</a>

[code]....

But when I use WebClient.DownloadString to read the source code to a textbox, I only get this:

<div id="webResults">
</div>

There's nothing. All of the webresults have been removed.How come I can view the code in my internet browser but not on my application?? I even used an InStr method to confirm that the results weren't contained in the generated code.

WebClient.DownloadString Not Getting Whole HTML String

Nov 11, 2010

I'm working on a project that scrapes data from government websites. I've noticed that whenever I use WebClient it doesn't always get the whole HTML code. Even when I get the robots.txt file it doesn't return everything. For example, http://www.bbc.co.uk/robots.txt has 80 lines but I'm only getting 13 lines.

If an HTML block uses "display: none" in the style I can't get anything between the hidden HTML blocks.Here is the sample code I'm using:[code]...

Html Source Code Doesn't Show Html But In Firebug Inspect Element Html Is There?

Jan 10, 2012

This may sound really stupid but I have to ask cause I'm not finding this answer anywhere.I have an application where the user will need to sign up for a new user account on the website [URL]..However when I am using Firefox's plug-in Firebug to view html I am getting something totally different than when I just right click on the site and view the page source.

What I am trying to do is to get the captcha from the website and display it in a picturebox on the application so the user can view the captcha, solve the captcha and then the app post is back to the service for a response.

Here is the source that I am getting using Firefox's Firebug to inspect the element:

<td>
<input type="hidden" value="Oo3Jo1I8bgzK68agMqo3s79ZZib2OkbK" name="iden">
<img class="capimage" src="/captcha/Oo3Jo1I8bgzK68agMqo3s79ZZib2OkbK.png" alt="i wonder if these things even work">
</td>

[Code]...

Why would the two be showing me two different versions of the HTML?

And how would you be able to grab that source to view in a picturebox using webclient?

VS 2010 Grab HTML Source Of Webpage And Set It As A Variable?

Dec 23, 2010

I decided it's time to migrate from VB6 to VB.NET and am currently translating my radio player but have run into several issues so I might be on this forum for the rest of the day... Anyway, in VB6 I used Inet to get the source of a PHP page that had the current song that was playing on the SHOUTcast stream. I can't seem to get Inet to work and figured I would just look for another method so I wouldn't need to pack msinet.ocx along with the finished product.

How can I get the source of the PHP page and store it in a variable or textbox/label.

I'm developing an app for WP7 and Win7 that will get info extracted directly from particular websites. The app will download the HTML source and parse through it to find the required strings. The strings may not have tags. note multiple instances of the string needs to be found. I've tried a few very rudimentary ways, and although they work, they are extremely slow.

Html - VB Basic RegEx - Save Value From An Input Tag In HTML Source Code

Feb 16, 2011

I am trying save a value from an input tag in some HTML source code. The tag looks like so:

<input name="user_status" value="3" />

I have the page source in a variable (pageSourceCode), and need to work out some regex to get the value (3 in this example). I have this so far: [Code] Which works fine most of the time, however this code is used to process source code from multiple sites (that use the same platform), and sometimes there are other attributes included in the input tag, or they are in a different order, eg:

<input class="someclass" type="hidden" value="3" name="user_status" />

I just dont understand regex enough to cope with these situations.
